CallableItem mixin

Provides the required methods for touch bar items that have methods or children that can have methods.

All the classes that uses this mixin must have its actions implemented following the example below:

class ClassWithAction extends AbstractTouchBarItem with CallableItem {
  // [onAction] store just an unique identifier of the implementation.
  final Identifier _onAction = Identifier.uniq();

  // The setter will change only the implementation stored in [methods].
  set onAction(Function newValue) {
    this.methods['$_onAction'] = newValue;
  }

  // [methods] will be used as single source of truth to the
  // implementation and [_onAction] will be
  // used in the [toMap()].
  ClassWithAction(Function onAction) :  super() {
    this.onAction = onAction;
  }
}

Properties

children → List<TouchBarItem>?

The subitems of this.

final, inherited

hashCode → int

The hash code for this object.

no setter, inherited

id → int

The unique sequential identifier of this.

final, inherited

methods → Map<String, Function>

Stores all the methods of this.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

type → String

Name of the touch bar item type that will be used to inform the specific platform implementation which TouchBarItem must be rendered/updated. This is important because the platform channel communication is performed through subset of the primitive types. See https://flutter.dev/docs/development/platform-integration/platform-channels#codec.

no setter, inherited

Methods

callMethod(String name, dynamic arguments) → bool

Searches the method named name in this and execute it.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toMap() → Map<String, dynamic>

Convert all the TouchBarItem data to a Map that will be used in the platform channel communication.

inherited

toString() → String

A string representation of this object.

inherited

updateProperty(String name, {dynamic newValue}) → void

Updates the property named name with a newValue.

inherited

Operators

operator ==(Object other) → bool
